Give this a shot. Tighten up all the lines. Take the lid off the master cylinder and make sure it's full. Crack your bleeder on the caliper. Brake fluid should ease out if there isn't a blockage anywhere. When it starts coming out the bleeder, cap it off. Go up to the master cylinder and you wanna prime it. What you wanna do is squeeze the handle just a little and release, enough you can see the brake fluid move around in the bowl. Keep doing that for a minute or so until all the air is gone. Little bubbles will pop up now and then if there's any there so go at it for a bit. Don't squeeze it hard and fast, it'll shoot like a watergun if ya do. Once the small movement is not producing any bubbles, squeeze the handle down, hold it down for a few seconds, then release. Sometimes little tiny bubbles wont come out with the small squeeze stuff so squeezing it hard a time or two will suds them up. some small squeezes after a hard press will sometimes pop them out.
Crack the banjo at the neck and let brake fluid run from the MC to the line, make sure you got a decent flow for a good 30 seconds, then cap it off. Move on to the bleeder, crack that open, put a hose on it and let it run for a bit. If any air is left the brake fluid will push it out the bleeder, you'll see it come out. Once you get a good flow and no air for 30 seconds, have someone help you bleed the brakes about 3 times and you should be good.
Works for me when I remove all the lines.
